Want a high-revving, F1-sounding, naturally aspirated V10 on a budget? Sounds impossible—until Jack and Diego from Build It Yourself made it happen. They took a humble Ford V10 truck engine, crafted custom four-valve heads, and engineered headers that deliver that unmistakable F1 scream.

In this episode of Tuned In, Jack and Diego share their backgrounds in automotive engineering and their journey into the performance automotive world. They discuss their current roles at Ford, the skills they bring to their YouTube channel Build It Yourself, and the innovative technologies they leverage, such as CAD, 3D scanning, and 3D printing.

The conversation dives deep into the highs and lows of building a one-off V10 engine. From the headaches of welding cylinder heads and perfecting cooling and oil flow to the science of exhaust sound engineering. They unpack machining, camshaft design, and the creative process behind documenting the entire build on YouTube.

Then there’s the bold decision to drop this beast into a 2017 Lincoln Continental, a choice that might not seem obvious to many enthusiasts. With the added challenge of a rear-wheel-drive conversion, it was definitely no straightforward swap.

What they’ve pulled off in their home workshop is nothing short of extraordinary. Blending solid engineering know-how with hands-on ingenuity, their Build It Yourself attitude is truly inspiring.

In this episode of Tuned In, Riccardo discusses his journey into automotive engineering and his role as an engine designer at Italtecnica, a company specialising in resto-mods, engine development, design, and manufacturing, working with brands like Ferrari and Maserati.

The conversation explores the evolution of Italtecnica, the challenges and innovations in resto-mod projects, and the range of engines currently being produced and developed. That includes a new naturally aspirated V12 for racing, along with a homologated version for road use. He also talks about the challenges of balancing power output with emissions compliance in modern engine design.

We dive into key fundamentals of engine design, including compression ratio, bearing clearance, rod-to-stroke ratio, cylinder head design, and different methods of valve actuation. The conversation also touches on the Atkinson cycle and how it can be replicated with variable valve timing.

It’s not every day you get to tap into the mind of someone designing bespoke high-performance engines from the ground up. This episode is jam-packed with insight and a must-listen for anyone interested in engine building.

Composites might seem like the secret language of aerospace engineers and hypercar builders, but Gabriel Mountjoy from Common Fibers is here to break down those barriers. He’s out to prove that composites aren’t just exotic materials—you can use them to elevate your own builds too.

In this episode of Tuned In, Gabe shares his journey from a mechanical engineering student passionate about automotive efficiency to a successful entrepreneur in the composites industry. Alongside his now-wife Ann, he co-invented the first carbon fiber hinge, and today their company is not only one of America’s leading composite manufacturers but also uniquely committed to educating people on how to work with these materials.

We explore the evolution of composites in automotive applications, the challenges and opportunities they bring, and why designing for manufacturability is key. Gabe also takes us inside high-profile projects like SSC North America’s Tuatara—a hypercar capable of 300 mph—explaining how they construct mission-critical, complex components such as its carbon-fiber monocoque.

Gabe breaks down the essentials of material and resin selection, unpacks layup methods, and clarifies the differences between wet layup, vacuum bagging, and resin infusion. He highlights the advantages of prepreg materials and compares autoclave with out-of-autoclave approaches.

Despite producing some of the most intricate composite parts in the U.S., Gabe and his team remain refreshingly open about their processes and deeply passionate about making composites more accessible.
